From b10af504a2015d12c566b6b0a4c7e3b602949eeb Mon Sep 17 00:00:00 2001 From: Nathan Lynch Date: Fri, 18 Nov 2022 09:07:40 -0600 Subject: [PATCH] powerpc/rtasd: use correct OF API for event scan rate rtas_token() should be used only for properties that are RTAS function tokens. "rtas-event-scan-rate" does not contain a function token, but it has the same size/format as token properties so reading it with rtas_token() happens to work. Convert to of_property_read_u32().
